Forum: movies Subject: Slow download times

Since late October, downloads have taken much, much more time than in the past and large MPEG2 files don't successfully download. Take for example the 1954 film "Salt of the Earth." I have tried to download this 3.2 GB file several times and each time, the process "hiccups" about 2/3 of the way through. Another happened this weekend. I started downloading the 2.32 GB file of "Boy, what a Girl!" at 8:43 on Friday, November 4. By Saturday afternoon, 1.63 GB had downloaded - more than 12 hours, and the computer seemed stalled. When I returned Sunday, 1.63 GB were still there. I stopped and then started the download again around 11 a.m. By 4 p.m., 1.21 GB had downloaded but this morning 1.82 had downloaded and the download had been interrupted sometime after 6:55 a.m. I am now trying a third time. I began at 7:30 this morning. Five hours later, only 1.44 GB have arrived on my computer and an estimated 3 more hours are required. I am using SAFARI and have downloaded files of 3 GB and more in the past without taking this much time or as many false starts. Neither IE nor Netscape will download files over 2 GB. Can someone tell me a way to solve this problem. I am working on a big project based on public domain films and I need to download at least 2 more MPEG2 files in the 3 GB size range today. At this rate, I am doomed.

Use a download accelerator with a resume function. All the Prelinger servers support resuming, so a "stalled" download won't break, as it frequently will using a browser. I use DOWNLOAD ACCELERATOR PLUS for all my Prelinger downloads.

Dear FP

This problem persists while using Dowload Accelerator Plus. I left the downloads running overnight and between 8 p.m. and 8 a.m. only 5% of the 2.38 GB file for the 1947 film Boy! What a Girl came through. I paused and resumed a few minutes ago and more is coming through now but only at 91 KB/sec.

Dare I suggest that something is amiss at the archive?

I'm getting full-speed downloads, meaning 1-3 megabits per second with DAP. Usually I can max out my DSL by downloading 2 films from Prelinger simultaneously. DAP opens up as many as 8 concurrent connections per file to the server and downloads a chunk of the file for each connection, then assembles them when all the chunks have arrived. It's even faster than ftp. It sounds as if your broadband connection may have a problem, or your firewall is barfing, or some other tech thing on your end. All I can say for sure is that Prelinger downloads are working okay here right now.

HI FP,

What do you mean "firewall is barfing?"

I think that the earthlink dsl might be part of the problem.

I mean that some setting on your firewall may be interfering with your Prelinger downloads. Shot in the dark guess.

I'm not familiar with Earthlink DSL. I use Verizon. Does Earthlink use packet-sniffing bandwidth throttling? I've heard some ISPs do that. They constantly analyze your traffic, and if an "abuse", as defined by them, is committed, your connection will be deliberately crippled.

Hi FP,

I use Verizon at my other location. This one, which is a share, has Earthlink. I spoke with Earthlink DSL earlier and they agree that connection is slow. I am set to speak with then again in ten minutes and will tell them that I routinely download multiple GB files so they'd better cut their throttling.

Thanks. Still don't get the barf thing but . . .

Say FP,

I found DAP for Mac OS X and downloaded a 14 day trial version. So far, I'm not seeing any improvement in speed. I'll leave the downloads running over night and I hope that I will have complete MPEGs tomorrow.

If you can tell me why this accelerator helps, I would appreciate it.

From your description, anything that allows you to resume (stop when you want and restart from that point) will help you, with or without speed increase. Using an ftp program with resume (typical of most) would also be a good strategy.

Hi Diana,

Thank you for your response. Though I have downloaded hundreds of Prelinger films, I don't have technical expertise about the process. What is an ftp program? Which would your recommend? How do I get it?

Using DAP helps with the resume function but how do I get the entire film to play. I played the first 8 minutes and then the mpeg file did not link to the remainder. The .tmp files are on the drive but I cannot access them.
